The unit includes all the driving gear train of the shaper to the bull gear, the forks controlling the gears and clutches, the shafts on which the forks "slide, and the handles and levers for making the gear shifts. All the driving 7 gears are carried on the two shafts 10 and 18.

Although I have illustrated and described only one form ofthe invention, I am aware of the fact that modifications can be made therein by any person skilled in'the art without departing from the scope of the invention as expressed in the claims.

Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is 1. In a driving gear unit for the purpose gear from said driven shaft, and means for simultaneously operating the clutch and gear r, shifting means, of a change speed gearbox havingmeans forchanging the speed, said gearingion the two shafts constituting means for doubling the range of the change speed gearing. I V 7 r 2., In a driving unit for speed change gear: ing, the combination of a driving anddriven shaft and change speed. gearing, all located on said two shafts,,with a driving pinion looselymounted on the driven shaft, means for clutching the saidrpinion to its shaft to be driven thereby, a gear fixed with respect to the driving pinion, a pinion fixed to the driven fixed to, the

shaft, a pinion onthe driving shaft slidable into andv out of mesh with said gear fiXedito thedriving pinion,a gear loose on the driving shaft constantly meshing with the pinion driven shaft, an internal rack on the gear loose on the drivingshaft adapted to mesh with said pinion on the driving shaft when thelat-ter meshes with the gear fixed to the loose pinion on the driven shaft, andmeans for simultaneouslyopenin'g the clutch and shifting the pinion on the driving shait to engage it with the gear on the driven s 1a t.i
